Research on Quantitative Analysis Method for Blending Polyester Fibers with Some Other Fibers(Alkaline Ethanol Method)
This article employs alkaline ethanol as a dissolving agent to quantitatively analyze polyester fibers and certain other fiber blended products.The analysis involves oscillating and dissolving the mixure in a 70℃water bath for 15 minutes,extracting polyster fibers from the known dry mass.The residue is then washed,dried,and weighed to calculate the mass percentage content of each component fiber.The national standard GB/T 2910.24-2009 Textiles-Quantitative Chemical Analysis-Part 24:Mixtures of Polyester and Certain Other Fibers(phenol/tetrachloroethane method)utilizes phenol/tetrachloroethane as the reagent.However,this reagent,possesses certain toxicity,has adverse effects on environment and human health and requires strict conditions for experimental environment and waste liquid recovery.In contrast,the alkaline ethanol method provides a more environmentally friendly and health-conscious alternative.With simple,accurate,and reliable procedures,it is well-suited for the quantitative analysis of polyester fibers mixed with certain other fibers.
